History
I started the building of the model at the beginning of the December, to the Christmas I built chassis, later I created the body. Because of creating the Fiat, I canceled my previous project – Mercedes SLS, becuse it wouldn't fit in the rules of the competition. If you don't know, how the original car looks like, here are the pictures.
Drivetrain
Fiat is driven by single RC motor. The gearbox is based on Sheepo's one from Veyron.
Gearbox ratio:
I 5:1
II 3:1
III 1,67:1
IV 1:1
To change gears I used 1 L motor. The ratio is 8:1 (worm gear). Fiat is a bit slow, because at the beginning I didn't want to exceed 1,5 kg of weight, and I hadn't got enough time to improve gear ratio or use 2 Xls.
Steering
For steering I used servo motor, which propel the gear rack 1x7 with ratio 1,67:1.
Suspension
The front and rear suspension is independent. I tried to make the rear like the real one, what you can see in the picture.
